6d69439f58 Call xxx_timer_initialize from clock subsystem
Call xxx_timer_initialize from clock subsystem to make timer ready for use as soon as possiblei and revert the workaround:

commit 0863e771a9
Author: Gregory Nutt <gnutt@nuttx.org>
Date:   Fri Apr 26 07:24:57 2019 -0600

    Revert "sched/clock/clock_initialize.c:  clock_inittime() needs to be done with CONFIG_SCHED_TICKLESS and clock_initialize should skip clock_inittime() for external RTC case since the RTC isn't ready yet."

    This reverts commit 2bc709d4b9.

    Commit 2bc709d4b9 was intended to handle the case where up_timer_gettime may not start from zero case.  However, this change has the side-effect of breaking every implementation of tickless mode:  After this change the tickless timer structures are used before they are initialized in clock_inittime().  Initialization happens later when up_initialize is called() when arm_timer_initialize().

    Since the tickless mode timer is very special, one solution might be to

    1. Rename xxx_timer_initialize to up_timer_initialize
    2  Move up_timer_initialize to include/nuttx/arch.h
    3.  Call it from clock subsystem instead up_initialize

    Basically, this change make timer initialization almost same as rtc initialization(up_rtc_initialize).

    For now, however, we just need to revert the change.

3e6c196ffa arch/ and config/ files: All board interfaces (those starting with board_) must be defined in board-specific logic. Otherwise, they cannot be customized of specialized usage by different boards. The board_reset() interface was defined in architecture-specific logic that only called up_systemreset(). That is useless!
This change removes the board_reset() implementation from the architecture-specific code and re-implements in the src/ directory of each board that has CONFIG_BOARDCTL_RESET enabled.  That is the correct functional partitioning.

2c93467436 pthreads: Add support static pthread stack. Add standard pthread_attr_setstack() and pthread_attr_getstack(). In all cases where the stack is released, add check to see which allocator must be used to free the stack: The user or the kernel allocator. 2018-08-23 09:49:20 -06:00

a465b6f0d4 configs/: Change CONFIG_BOARD_RESET_ON_CRASH to CONFIG_BOARD_RESET_ON_ASSERT, arch/: Implement call to board_reset() if in all implementations of up_assert() when CONFIG_BOARD_RESET_ON_ASSERT=y. 2018-08-22 17:04:39 -06:00

c790450ba2 Remove CONFIG_ARCH_CALIBRATION. It is awkward to use and no longer necessary now that we have apps/examples/calib_udelay. 2018-08-19 10:06:36 -06:00

f2a89813f2 Build system: Remove fixed lib/ subdirectory and its content. Replace with new directory called staging/ that is created dynamically when building and removed when 'make clean' is done. This both improves the name and eliminates a garbage directory from the repository. 2018-05-29 11:36:21 -06:00
